Help me find x please

Sedaia [141]

Answer:

$\displaystyle 13 = x$

Step-by-step explanation:

All three angles in an equilateral triangle are equivalent, and they sum up to 180°, so each angle measures 60°:

60° = [8x - 44]°

+ 44° + 44°

____________

$\displaystyle \frac{104°}{8} = \frac{[8x]°}{8} \\ \\ 13° = x$

The endpoints of a diameter of a circle are (4,-2) and (3,6). Find the area of the circle in terms of pi

Vinil7 [7]

The endpoints of a diameter of a circle are (4,-2) and (3,6). The area of the circle in terms of pi is 65pi
First, is to get the length of the diameter by getting the distance of the two points: (4, -2) and (3, 6)

dis = sqrt( (x2-x1)^2 + (y2-y1)^2)
dis = sqrt( (3-4)^2 + (6--2)^2 )
dis = sqrt( 1 + 64 )
dis = sqrt(65)

Next, is to find the area of the circle:
A = pi * r^2
A = pi * (sqrt(65))^2
A = 204.20 square units

ddd [48]

The circumference of a circle is $2\pi r$ and it coresponds to a 360 degree angle.

The circumference of the circle is 2*4*pi=8pi m=25.12m

25.12m......360 degrees
10 m.........x degrees
x=10*360/25.12=143.31 degrees
